Can you make your own essential oils?
Making your own bio essential oil is possible if you respect certain very strict rules of caution when handling them because they are powerful products. The quintessence of the plant is extracted at different levels: flowers, leaves, stems, roots or twigs. To do this, there are several manufacturing methods.
Distillation of essential oils
After harvesting fresh and mature plants, it is necessary to let them dehydrate in an open and shaded area. A hydro-distillator (30, 40 or 50 litres) and preferably spring water must be available. Then the oil will be bottled in an opaque brown or blue glass.
Cold mechanical expression
Citrus essences are obtained in this way at room temperature without distillation: the zests are pressed.
Vegetables are left to macerate in volatile solvents, which, after vaporisation, produce a pét; it will be diluted in thylique alcohol and filtered. This operation concerns bark, seeds or spices.
The flowers are placed on a frame that has previously been covered with refined animal fat. This grease will absorb the smell of the flowers for 3 months. This fat, which has been transformed into an ointment, will then be collected, mixed with alcohol and then vacuum distilled to produce the product.
This enfleurage can also be made hot by melting the fat in the water bath and discarding the flowers. We stir, renew the operation and filter.
These ancestral methods still persist in countries where essential oil enthusiasts consider this the best way to obtain products of unequalled quality.
These different craft methods allow those who practice them to carefully choose vegetables, use utensils that they have carefully maintained and thus be certain of the quality of the product they have manufactured. These methods are certainly laborious, but they testify to a real know-how.
